Application filed August 27, 1909.

Patented May 31, 1916. Serial No. 514,849.

To all whom it may concern:

Be it known that I, THOMAS A. DE VILBISS, a citizen of the UnitedStates, and a resident of Toledo, in the county of Lucas and State ofOhio, have invented a certain new and useful Dropper; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to instruments adapted to facilitate a dropping ofliquids from bottles or the like, and has particular reference to use inconnection with instruments adapted for the spraying of perfumes or thelike, but, is not restricted to such use, as it may be employed in anyconnection for which it may be adapted or appropriate.

The object of my invention is the provision of an improved apparatus ofthis class, which is simple and inexpensive in its construction,efiicient in its operation, and

' capable of being easily and quickly removed from one and inserted intoanother bottle or liquid receptacle, thus particularly adapting it foruse by perfume demonstrators or the like, and which is capable of beingsealed against leakage to facilitate a packing of the Samewithoutliability of liquid escaping from an associated receptacle.

The operation, construction and arrangement of the parts of theinvention are fully' described in the following specification, and apreferred embodiment thereof illustrated inthe accompanying drawings, inwhich,

Figure l is acentral vertical section ofan apparatus embodying myinvention and an associated liquid receptacle, and Fig. 2 is a form orconstruction. Extending down into the bottle \to near the bottom thereofis the usual liqdid-tubje 2, which carries a stoppermember for closingthe neck of the bottle and holding such tube in suspension therein. Thisstopper-member is shown in the present instance as comprising a sleeve3, which fits closely around the tube 2 near its upper or outer end, anda tapered member at of cork, rubber or other suitable material, whichclosely encircles the sleeve 3 and is adapted to fit tightly within theneck of the bottle to close the same. The sleeve 3 is flanged orenlarged at its upper end as at 5, to abut againstthe member 4, andpreferably pro jects slightly beyond the upper end of such member toserve-as a stop for limiting the insertion of the stopper within thebottle neck. position on the sleeve 3 by a nut 6, which is threaded tothe lower end of the sleeve. 2

Threaded or otherwise suitably secured to the upper endof the tube 2 isa spray-head 7, which has a vacuum chamber 8 on one side thereof and isbored, as at 9, to open communication between such chamber and the\liquid-tube 2, and as at 10 to open (@111- munication between suchchamber and the air-supply-tube 11. This tube attaches at one endtolsaid head and leads to any suitable source of air pressure, such, forinstance as an air-bulb 12. It is apparent that when air is forced underpressure through the bore 10 the discharge from the chamber 8 throughthe alining discharge orifice 13 creates a vacuum or suction within suchchamber and a consequent drawing of liquid therein from the bottle 1through the tube 2- and bore 9, which liquid commingles with the air andis discharged thereby in spray form from the head, as is common withinstruments of this class.

In order to prevent a vacuum within the bottle when the liquid is drawntherefrom, air is admitted thereto. throu h a channel 14 in thestopper-memberf Tins chamber is shown in the present instance as beingformed by providing a longitudinal depressionor groove in one side ofthe tube, such depression extending through and being of greater lengththan the stopper-member to open without the opposite ends thereof, asshown.

To prevent leakage of the contents of the bottle through the channel liwhen the instrument is acked the spray-head 7 may be removed rom thetube 2 and a cap 15, Fig. 2, screwed thereover. The base of this capseats cl y on the top of thefiange or enlargemen 5 of the sto per-memberand closes the outerend of t e channel 14, as"

The cork or member 4 is retained in strument as a dropper for liquids orto shake the contents therefrom, the cap 15 can be unscrewedsufficiently to unseat it and partially uncover the outer'end of thechannel 14: to adapt it for such uses.

It is apparent that I have provided an instrument which is not onlyhighly efficient for .use either as an atomizer or dropper, but which isexceedingly simple in its construction and adapted for easy and quickapplication to or removal from the neck of any bottle for which it maybe adapted.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of parts except in so far as suchlimitations are specified in the claims.

Having thus described'my invention, what I claim as new and desire tosecure by Letters Patent, is,--

1. In an instrument of the class described, a receptacle, a tubeprojecting into such receptacle, a stopper-member carried by the tubeand adapted to. close the neck of the receptacle, said stopper-memberhaving a channel therethrough at the side of the tube which'openscommunication between the illterior of the receptacle and theatmosphere, and a member adapted to thread over the outer end of saidtube and to seat on the outer end of the stopper-member to close saidchannel and to be unseated to a predetermined extent to permit theshaking of liquid from the bottle through said channel.

2. In an instrument of the class described, a receptacle, a memberclosing the neck of mined extent to permit a shaking o the con- 7 tentsof the bottle therefrom through said channel.

3. In an instrument of the class described, a receptacle, a member forclosing the neck of the receptacle, a sleeve projected throughsaidmember, a liquid tube projected through said sleeve and into thereceptacle and having its outer end open and adapted to carry anatomizer spray-head, said. tube having a portion longitudinally saidreceptacle, a tube rojected through depressed to provide a channelbetweenthe sleeve and tube from the interior of the receptacle. to theexterior of said member, and a cap threaded to the outer end of saidtube and adapted to close the outer end thereof and, when seated on theouter end of said sleeve, to close said channel, substantially asdescribed.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
